SPECIFICATION forming part of Letters Patent No. 710,559, dated October '7, 1902.

Application tiled December 13, 1900. Serial No. 39,589. (No model.)

To all 1071/0771, t petty concern:

Be it known thatwe, CHARLES XY. BECK, residing at New York city, New York, and WILLIAM C. HOMAN, residing at Meriden, Connecticut, citizens of the United States, have invented certain new and useful Improvements in Acetylene-Generators,of which the following is a full, clear, and exact description.

Our invention relates to certain new and useful improvements in gas-generators particularly useful in lamps and small generating apparatus. In devices of this character the gas is automatically generated and fed to the burner; and it is the object of our invention to provide a simple and effective means whereby the user may manually shut offthe flow of gas through the outlet-pipe and at the same time shut off the communication between the gas-generating elements, so that there will be no after generation of gas. Vhen it is again desired to use the generator, the user may open the gas-outlet, whereupon the communicating passage between the gasgenerating elements is opened, so that gas may again be generated.

In the drawings we have illustrated a generator in the form of a lamp, in which automatic means is provided whereby the gasgenerating elements may be brought together so as to gradually produce the proper quantities of gas. This, it will be seen, in the particular forxn shown is accomplished by automatically controlling a valve between the carbid-chamber and the duid-chamber, the said valve being controlled by a diaphragm. The pressure of the gas within the lamp varies the operative position of the diaphragm, so that it in turn may regulate the position of the feed-valve for the carbid.

In the drawings, Figure 1 is a side elevation, partly in section, of a portion of a lamp provided with our improved controlling apparatus. Fig. 2 is a plan view of our controlling apparatus and the parts associated therewith, partly in section. Figs. 3 and et are detached views of details of construction.

A is a water-reservoir. B is a carbid-receptacle above said reservoir.

C is a feed-valve.

D is a valve-seat.

E is a valve-stem connected to adiaphragm F of a collapsible gas bag or chamber F.

F2 is a partition within the generator, forming a space for the gas-bag.

G is a spring connected to the gas-bag in such a way that it will cause the saine to eol lapse, except when under pressure.

H is a tube surrounding the valve-stem E and spring G, partly as a protection therefor and partly as a supporting means for the staf tionary end of the spring Gr. The tube H forms a gas-passage into the gas-chamber F, and it may have supplemental gas-passages H', if desired.

I is a lever connected with the movable portion of the gas-ehamber-the diaphragm F'. This lever I is fulcrumed at J. In the drawings this lever is shown to be bifurcated, so that its two forked members engage on opposite sides of the valve-stem, whichis shown as passing through and xed to the diaphragm FC At a suitable point on the leverarms I there is an arched portion or yoke I. (See Fig. 4..)

K is a valve-rod.

K is a valve.

L is a valve-seat in a passage for the gas leading from the gas-chamber F to theburner M. N is a flexible tube which may form part of said gas-passage.

In order to render the generator perfectly safe, we have devised a means whereby the carbid-feed is checked at the same moment the gas is turned offin the outlet-pipe, softhat aftergenerationisprevented. Consequently the lamp may be set to one side with perfect safety until it is desired to use it again. Ve have described the means for turning off the gas in the' outlet-passage, and we will now proceed to describe the means coacting therewith for closing the carbid-feed.

In the drawings, O is a camcarried by the Valve-stem K, which cam cooperates with the yoke I, so that when the valve-stem K is rorated it will quickly lift said yoke, and thereby the lever-arms I, which in turn quickly expand the gas-bag G, moving the valve-stem E and bringing the valve Cinto contact with the valve-seat D, thereby shutting o communication between the carbid and iiuid chambers and preventing the after generation of the gas. In a lamp this quick expansion of the collapsible gas-chamber causes a slight suction, which extinguishes the ame at the burner instantaneously. inasmuch as the valve K closes the passage to the burner, any gas that may be contained within the lampis imprisoned until it becomes desirable to light the lamp again, whereupon the moment the valve is opened this retained or imprisoned gas iiows to the burner and may be instantly ignited. This is a desirable feature, because it is not necessary to wait for the generation of the new gas-supply.

While we have shown and described this invention as in connection with a gas-lamp, it is obvious that it has its advantages in connection with acetylene-gas generators at large.

The partition F2 forms a separate space for the collapsible gas-bag F, so that the diaphragm-that is, the means which controls the valve C-may be variably positioned by the pressure within the generator, which pressure is transmitted to the diaphragm.

IThe valve rod or stem K is by preference screw-threaded when the form of valve K shown in the drawings is employed. Obviously this particular form of valve is immaterial.

Other modifications may be made without departing from the spirit of the invention, as it should be understood that we do not intend to limit ourselves to the specific-details of construction shown in the drawings. For example, instead of employing a cam for operating the diaphragm -controlling lever any well-known mechanical means might be substituted that would accomplish the desired end.

It' a leak should be developed within the apparatus or if for any reason it should temporarily fail to work properly, the user may instantly turn off the gas, whereupon the carbid-feed would be closed and locked, and he may thereupon proceed to correct the defect, or he may set the apparatus aside with perfect safety untilsuch time as itis convenient to make the necessary repairs.
